Title: Improvements in the separation of soluble substances
IPC: B01D9/00
Filed: 1929-03-14
Abstract: 334,169. Imperial Chemical Industries, Ltd., and Cocksedge, H. E. March 14, 1929. Wet-separating.-Soluble substances are treated by simultaneous crystallization from a common solution followed by mechanical separation. The separation may consist in first grading by size e.g. by sieving and then by density e.g. by elutriation in an inert liquid, or the size of the particles of one or both of the substances may be controlled during crystallization by seeding, addition to super-saturated solutions, or the addition of colloids such as gelatine, and the mixture of crystals separated by a single grading which may be either sieving or elutriation. Instead of elutriation grading by density may be effected by pneumatic means, centrifugal action, or Wilfley table action. Examples are given of the separation of sodium nitrate and potassium nitrate by sieving followed by elutriation in a solution saturated with both salts, and of sodium carbonate and sodium chloride by control of particle size during crystallization followed by sieving or elutriation or both. In the example the control of particle size is effected by seeding with small crystals of sodium chloride produced in the solution by shock cooling. Specifications 144,022; and 322,480, [Class 117, Sifting &c.], are referred to.

Title: Improvements relating to coin-freed apparatus
IPC: G07F11/16
Filed: 1925-03-30
Abstract: 254,773. Millar, W. R. March 30, 1925. Delivery of articles stored in piles.- Articles stored in two columns m, Fig. 4, are delivered from one column at a time by pulling out and then pushing in either of two handles R, R', Fig. 1, after the insertion of a coin in a single coin slot a<1>. The handles operate bars Q, Q' carrying delivery traps G, G' and both trays are prevented from being actuated at the same time by a cam A on a sliding bar H, releasable by the coin and located between the bars Q, Q<1>, the bar H not being mechanically connected to the other bars. When the handle R, for example, is pulled, a pin E on the bar Q engages one side of the cam A which swivels on a pin D so that its nose A<4> passes to one side of a blocking pin D. The other side of the cam blocks a pin E<1> on the bar Q' thereby locking the delivery tray G<1>, and the cam also turns about the pin E<1> as a fulcrum thereby moving the coin bar H against the action of a coiled spring attached to the pin D. The pin E then travels along a plain portion A<3> of the cam and the tray G carries the bottom article forward. When the handle R is pushed back, the pile pushes the bottom article off the tray to drop down a shoot i to a delivery opening z. The coil spring completes the return of the tray after it is partially pushed back. The complete return of the trays, before another actuation, is ensured by pawls S, S<1>, Fig. 1, adapted to engage fixed ratchet teeth M, M<1>, the pawls carrying floating pawls T, T' which are actuated by dents or depressions N, N<1>. A weighted flap g at the bottom of each magazine m prevents fraudulent abstraction of the articles. Coin action, mechanical - connection and multiple-coin.-The coin passes to a slot L in a pivoted detent I and rests in a slot in the coin bar H. When the bar H is pulled the edge of the coin raises the detent I and disengages its nose from a notch J in the bar. When goods of different values are delivered requiring two different coins, a double coin shoot is used and the coin bar and detent is split as shown in Fig. 7. The split coin bar is attached to the cam by a link A' having slots 23, 23<1> in which pins E<3>, E<2> on the halves H<1>, H<2> of the coin bar work. Coin-slit closing-devices; "empty" notices, displaying.-The goods in the magazine actuate flaps l, Fig. 4, connected by links x to cranks n. These cranks are connected bv links x, Fig. 6, to a rocking bar s, from which depend rods r carrying " empty " notices g to show through a window p. When one magazine is empty, the bar s is rocked about one end to expose a notice q and raise a pin u from its normal position u<1> up to the coin slot. When the second magazine is empty the other notice is displayed and the pin u is moved across the slot a<1> to a position u<2>. Casings.-The casing of the machine is made with deep recesses and rounded corners. The articles sold are advertised by means of models fixed to the top of the case.

Title: Improvements in or relating to a process for vapor phase hydrogenation of the saturated compounds
IPC: C07C5/10
Filed: 1947-04-01
Abstract: In the vapour-phase catalytic hydrogenation of unsaturated compounds, e.g. the hydrogenation of benzene to cyclohexane, and of other aromatic hydrocarbons, phenols and olefines, the reaction temperature is controlled by circulating a heat-exchange fluid in contact with the walls of the catalyst-containing units and by passing the reactant vapours in admixture with an inert gaseous diluent in the proportion of at least 2 mols. and less than 10 mols. of diluent to each mol. of the unsaturated compound through the catalyst at a pressure sufficient to suppress the reverse reaction.  Specified gaseous diluents are nitrogen and the reaction product, e.g. cyclohexane.  When the reaction product is employed as diluent it may be recycled prior to condensation or it may be first condensed, then revaporized and recycled.  The heat of reaction, as absorbed by the heat-transfer fluid, may be employed to vaporize the unsaturated compound and also the reaction product when the latter is employed as diluent. Specification 629,405 is referred to.ALSO:In the vapour-phase catalytic hydrogenation of unsaturated compounds, e.g. the hydrogenation of benzene to cyclohexane, the reaction temperature is controlled by circulating a heat-exchange fluid in contact with the walls of the catalyst-containing units and by passing the reactant vapours in admixture with an inert gaseous diluent in the proportion of at least 2 mols. and less than 10 mols. of diluent to each mol. of the unsaturated compound through the catalyst at a pressure sufficient to suppress the reverse reaction.
